When the Blackhawks’ Patrick Sharp and the Los Angeles Kings’ Justin Williams dropped their gloves and started to fight in the first period of Game 3 of the Western Conference finals Tuesday, it was hardly the likeliest bout in NHL history. The two have played a combined 22 seasons in the NHL and have a combined 11 fights, according to hockeyfights.com. Sharp has had seven, but none since January 2009. Officials broke up the fight — which started as the two shoved each other while jockeying for position on a faceoff — before it got started, and each received only a roughing minor. But Sharp said he would be happy to continue what they started later in the series. ‘‘He asked me to fight,’’ Sharp said. ‘‘If he asks me again, I’ll fight him any day he wants.’’ The Kings laughed it off. ‘‘[Williams] is pretty tough undercover,’’ Kings enforcer Kyle Clifford said. ‘‘I wouldn’t mind seeing that.’’
